Title: Integrated synchronizing signal separating circuit
Inventor: OKADA YOSHINORI
IPC: H02M5/27
Filed: 1982-04-14
Abstract: PURPOSE:To reduce power consumption, by providing a clipping circuit on the prestage of a feedback type clamping circuit, and driving a synchronizing signal separating circuit by low voltage. CONSTITUTION:A clipping circuit 36 is provided between a differential amplifier 43 for amplifying an inputted video signal 30, and a feedback type clamping circuit 31 for specifying a synchronization separating threshold level to the video signal 30. The inputted video signal 30 is supplied to the base of a transistor 3 of the clamping circuit 31 through the differential amplifier 43, but in this case, its base-applied signal 44 becomes a waveform obtained by a fact that a video part of the video signal is clipped by the clipping circuit 36. The signal is supplied to the base of a transistor 8 through the transistor 3, therefore, amplitude of a base signal of the transistor 8 becomes small by the clipped video signal. Accordingly, supply voltage 27 can be reduced by the video signal portion as compared with conventional methods.

Abstract: PURPOSE:To form oxide films of the same thickness on the bottom surface and the sidewall of a groove, and make it easy to control the characteristics of a semiconductor element formed in the groove, by forming the groove on the basis of an orientation flat formed on a substrate when the groove is made on the silicon substrate surface and therein the semiconductor element is formed. CONSTITUTION:On a silicon substrate 18, a groove is formed, and on the peripheral wall of the groove, an oxide film is stuck. When a semiconductor element is arranged in a part surrounded by the film, it is formed on the basis of an orientation flat wherein a groove is formed on the substrate. In the case of (100) face of a substrate, the orientation flat is formed in the direction of <100>. In the case of (110) it is formed in the direction of <110> or <100>. In the case of (210), it is formed in the direction of <210> or <100>. For example, when the surface of the substrate 18 is a (100) face, a flat 18a is formed on the periphery in the direction of <100>, and a groove 19 is made on the basis of it. Thereby, the bottom surface and the side surfaces of the groove 19 are all the (100) face, and the thickness of an oxide film stuck on these surfaces is made uniform.

Title: Radio-wave azimuth detector
Inventor: OOMAE TAKAO
IPC: G01S3/48
Filed: 1978-05-22
Abstract: PURPOSE:To judge the arrival direction of a radio wave from the phase difference of a received signal, by arranging two array antennas, composed of non-directional antennas, at right angles. CONSTITUTION:Antenna element 1 is non-directional and available to receive a radio wave in any direction. However, only arranging them in a line results in that an azimuth can not be detected because there may be an angle where an arrival radio wave becomes in phase depending upon its direction. For the purpose, two array antennas 2a and 2b are arranged crossing at right angles to detect the arrival azimuth in every direction judging from the received signals, and array antennas are arranged on a vertical plane to detect the azimuth and wave angle.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To prevent the reciprocation of a piston rod caused by its forward displacement and to prevent the generation of the excess stress on a front spring by expanding only a rear spring chamber during the work. SOLUTION: A rear spring chamber R3 and a front spring chamber R4 can communicate with a front cylinder chamber R1 or a rear cylinder chamber R2 through an exhaust passage 44 by forming a rear spring chamber vent hole J3 and a front spring vent hole J4.

In this case, the primary polishing is ended when the current between the wire 4 and the cathode goes zero or close to zero. Next, the wire 4 after the primary polishing is again immersed in the liquid 2 and while the wire 4 and the liquid level are being vertically moved 0.5W5.0mm relative to each other, the end part is electrolytically polished in the same manner as that in the primary polishing. In this case, the voltage is applied until the current flowing from the wire 4 goes zero. The worked product obtained by this is used for needles for acupuncture or the like.

Abstract: PURPOSE:To realize the emphasis method of a picture data able to emphasize only a contour of a signal component without emphasizing a noise component scattered uniformly on a pattern. CONSTITUTION:Peripheral picture element data B11-B21, B23-B33 are read in steps ST1-ST8 and the mean value XA is obtained in the step ST9.

Title: Tape recorder
Inventor: SHIMADA HIROMICHI
IPC: G11B15/04
Filed: 1985-03-27
Abstract: PURPOSE:To attain mode operation changeover without troublesome operation easily and mis-operation by adopting the constitution that an old modememory section discriminates the mode just before the transition to the forward/reverse recording mode and the mode is transited once to the stop mode once. CONSTITUTION:When a forward switch 13 is depressed with a present mode memory section 41 selected to the reverse recording mode, the old-mode memory section 42 representing the mode just before is in the reversing mode, then the mode is transited once to the stop mode by the control of a mechanism section 20 to avoid accidental erasure of the already recorded part. When the content of the memory section 42 is in the stop or pause mode, the mechanism section 20 applies the control to be transited to the forward mode to eliminate the need for a troublesome operation. When the forward recording is desired during the reversing mode, since the mode is transited once to the stop mode, the mode can be moved to any mode next. Thus, the mode changeover is applied easily without error.

Filed: 1995-03-22
Abstract: PURPOSE: To reduce the time up to phase locking when a phase comparator and a frequency divider transit from the off-state into the on-state. CONSTITUTION: In the initial state when a frequency divider C and a phase comparator A being peripheral circuits arise from the off-state into the on-state when a variable frequency oscillator B is in the on-state and the peripheral circuits are in the on/off intermittent state, a leading control signal 6 rises at an input of a phase initializing circuit D and an input clock signal 1 rises, then the circuit D provides an output of a signal 5 to reset the frequency divider C at a leading edge of the signal 1. Then, the frequency divider C outputs a comparison clock signal 2 reset by the signal 5. In this case, the phases of the signals 1, 2 are made coincident. When the phases of the signals 1, 2 are coincident, a phase comparison rising signal 7 is outputted from a rising control circuit E having received the control signal 6 to activate the phase comparator A which starts phase comparison.
